This was specially requested by my friend Ben. I knew it wouldn't be a long video, because part of the joy of the Roomba is that it cleans under the couch -- a place where a camera taped on top won't fit. But still, this gives you an idea how the Roomba starts its job of cleaning the floor: it sings a song, and then spirals out from the center of the room, sucking up little bits as it goes.
